I am using RMAN to duplicate our live DB to another identical
machine. Full On-line backups are taken 5 days a week (file is 25Gb on
disk), each one includes *all* archive logs.

I have been asked to see if we can use a different nights backup
for the duplication process, other than the last backup taken. I can't
find anything on MetaLink and Rob Freemans book only mentions that
Duplicate uses the last good backup.
